3. Analytical and Sampling Methods for Monitoring <br />PART I <br />Page 10 of 26 <br />Permit No.: C00036251 <br />permit and, unless otherwise specified, before the effluent joins or is diluted by any other <br />wastestream, body of water, or substance. Monitoring points shall not be changed without <br />notification to and approval by the Division. <br />The permittee shall install, calibrate, use and maintain monitoring methods and equipment, including <br />biological and indicated pollutant monitoring methods. All sampling shall be performed by the <br />permittee according to specified methods in 40 C.F.R. Part 136; methods approved by EPA pursuant <br />to 40 C.F.R. Part 136; or methods approved by the Division, in the absence of a method specified in <br />or approved pursuant to 40 C.F.R. Part 136. <br />If the permit contains a numeric effluent limit, the analytical method and PQL selected for a <br />parameter shall be the one that can measure compliance with the numeric effluent limit. If all <br />analytical methods and corresponding PQLs are greater than the numeric effluent limit, then <br />the analytical method with the lowest PQL shall be used. <br />If the permit contains a monitoring or report only requirement, the analytical method chosen <br />shall be one that can measure to the potential numeric effluent limit(s) (maximum allowable <br />pollutant concentration as shown in the WQA or fact sheet). If all analytical methods and <br />corresponding PQLs are greater than the potential numeric effluent limit (s), then the <br />analytical method with the lowest PQL shall be used. <br />If the permit contains an interim effluent limitation (a limit is report until such time as a <br />numeric effluent limit becomes effective), the analytical method chosen shall be one that can <br />measure to the final numeric effluent limit. If all analytical methods and corresponding PQLs <br />are greater than the final numeric effluent limit (s), then the analytical method with the lowest <br />PQL shall be used. <br />When the analytical method which complies with the above requirements has a PQL greater <br />than the permit limit, the permittee shall report "BDL" on the DMR. Such reports will not be <br />considered as violations of the permit limit, as long as the lowest available PQL is used for the <br />analysis. When the analytical method which complies with the above requirements has a PQL <br />that is equal to or less than the permit limitation, "< X" (where X = the actual PQL achieved by <br />the laboratory) shall be reported on the DMR. For parameters that have only a monitoring or <br />report only limitation, "< X" (where X = the actual PQL achieved by the laboratory) shall be <br />reported on the DMR. <br />The present lowest PQLs for specific parameters, as determined by the State Laboratory (November <br />2008) are provided below. If the analytical method cannot achieve a PQL that is less than or equal to <br />the permit limit, then the method, or a more precise method, must achieve a PQL that is less than or <br />equal to the PQL in the table below. A listing of the PQLs for organic parameters that must meet the <br />above requirement can be found in the Division's Practical Quantitation Limitation Guidance <br />Document, July 2008. <br />These limits apply to the total recoverable or the potentially dissolved fraction of metals. <br />
